Description

Technical Field

[0001] This utility model relates to the field of UWB antenna technology, specifically to a novel high-gain UWB antenna. Background Technology

[0002] With the development of communication technology, UWB technology has advantages such as low system complexity, low transmitted signal power spectral density, insensitivity to channel fading, low interception capability, high positioning accuracy, and strong penetration capability. It is particularly suitable for high-speed wireless access in dense multipath environments such as indoor spaces, and is beginning to be widely used in positioning, ranging, and radio stations. An ultra-wideband antenna is an antenna specifically designed for use with ultra-wideband communication technology, a wireless communication technology that uses a very wide spectral bandwidth to transmit data, typically operating in the frequency range of 3.1 to 10.6 GHz. This technology has attracted attention due to its low power consumption, high data rate, and positioning accuracy, especially in indoor positioning and wireless communication fields.

[0003] A small dual-notch ultra-wideband antenna, disclosed in CN105356042A, addresses the issue of large size in existing notch ultra-wideband antennas. It includes a dielectric substrate, a radiating patch printed on the lower longitudinal axis of the substrate, and a ground plane on the lower surface. The radiating patch employs a step structure with symmetrically arranged mushroom-shaped EBG structures on both sides, each etched with meandering bends. A wide slot is located in the middle of the ground plane, with four-armed spiral slots symmetrically etched on its upper sides. The mushroom-shaped EBG structures are connected to the ground plane via metallized vias. This invention features small size, wide bandwidth, and excellent notch filtering performance, making it suitable for use in ultra-wideband wireless communication.

[0004] Shortcomings of existing technology: Existing UWB antennas suffer from high transmission loss due to their high frequency, resulting in insufficient signal transmission distance. In addition, some frequency bands overlap with WiFi, causing interference problems that affect the user experience and thus the signal transmission distance and quality. Utility Model Content

[0005] Therefore, this utility model provides a novel high-gain UWB antenna to solve the problems of short antenna signal transmission distance and poor quality caused by high transmission loss and overlap of some frequency bands with WiFi in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel high-gain UWB antenna, including a connection mechanism, and further comprising:

[0007] The antenna body, located at the top of the connecting mechanism, is used to improve the distance and quality of signal transmission.

[0008] The antenna body includes a substrate, a radiator is fixedly installed on one side of the outer wall of the substrate, a microstrip line is fixedly installed on the bottom of the radiator, and a U-shaped groove is formed at the bottom of the radiator near the microstrip line.

[0009] The connection mechanism includes an inner core welded to the microstrip line, a connecting seat fixedly installed at the bottom of the inner core, and an external threaded connector fixedly installed at the bottom of the connecting seat.

[0010] Preferably, a reflector is fixedly installed on one side of the outer wall of the substrate, and a reflective arc surface is provided on one end of the outer wall of the reflector.

[0011] Preferably, the reflective arc surface and the radiator are concentric, and two first ground planes are fixedly installed on one bottom side of the substrate, with the two first ground planes respectively disposed at both ends of the microstrip line.

[0012] Preferably, a second grounding plate is fixedly installed on the outer wall of the substrate on the side away from the first grounding plate, and a plurality of connecting terminals are fixedly installed on the top of the connecting seat, and the plurality of connecting terminals are respectively connected to the first grounding plate and the second grounding plate.

[0013] Preferably, each of the two first ground planes has a connecting bolt threaded into its top, and the two connecting bolts pass through the substrate on the side away from the first ground plane and are threadedly connected to the second ground plane.

[0014] Preferably, the top of the first grounding plate is at the same height as the top of the second grounding plate, and the second grounding plate is configured as a U-shaped structure.

[0015] Preferably, the height of the reflective arc surface is greater than the height of the radiator.

[0016] This utility model has the following advantages:

[0017] 1. This utility model connects the connecting mechanism and the radiator by welding the inner core and the microstrip line, thereby enabling the antenna body to work stably. The U-shaped groove on the inside of the radiator can form a notch structure, which can filter out the 5G frequency band that overlaps with WiFi. At the same time, the reflective arc surface at one end of the reflector can concentrate the antenna energy, improve the antenna gain, and thus improve the signal transmission distance and quality, thereby enabling the antenna to transmit signals more stably.

[0018] 2. This utility model uses a connecting bolt threaded through the first ground plane and the substrate and threadedly connected to the second ground plane, so that the first ground plane and the second ground plane can be stably installed on the surface of the substrate. This makes it convenient for workers to install and replace the first ground plane and the second ground plane. The connection between the connecting terminal and the first ground plane and the second ground plane allows the antenna to work stably. Attached Figure Description

[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Refer to the instruction manual appendix Figure 1This utility model provides a novel high-gain UWB antenna, including a connecting mechanism 2, and further comprising:

[0029] The antenna body 1, located at the top of the connecting mechanism 2, is used to improve the distance and quality of signal transmission. Compared with traditional UWB antennas, it can filter out 5G signals that overlap with WiFi and concentrate the energy of the antenna, thereby improving the antenna gain. This enables the antenna body 1 to achieve high-quality signal transmission over long distances, with a gain approximately 3dB higher than that of traditional antennas.

[0030] To avoid WiFi signals interfering with antenna operation, such as Figure 1 and Figures 3-4 As shown, the antenna body 1 includes a substrate 101. A radiator 102 is fixedly mounted on the outer wall of one side of the substrate 101. A microstrip line 103 is fixedly mounted on the bottom of the radiator 102. A U-shaped groove 104 is formed at the bottom of the radiator 102 near the microstrip line 103. The connecting mechanism 2 includes an inner core 203 welded to the microstrip line 103. A connector 202 is fixedly mounted on the bottom of the inner core 203. An external threaded connector 201 is fixedly mounted on the bottom of the connector 202. The connecting mechanism 2 is connected to the radiator 102 by welding the inner core 203 to the microstrip line 103. The main body of the radiator 102 is a circular metal. The radiator 102 transmits electromagnetic waves... The antenna transmits signals through radiation. The U-shaped groove 104 inside the radiator 102 filters out 5G signals that overlap with WiFi, thereby improving the signal transmission distance and quality. The external threaded connector 201 allows the antenna to be easily connected to other devices, enabling the antenna body 1 to work stably. The connection mechanism 2 is an SMA connector, which can undertake high-frequency signal transmission tasks. Its compact design and anti-interference capabilities are suitable for the high stability requirements of UWB communication, thus enabling the antenna body 1 to transmit signals stably and ensuring the quality of signal transmission.

[0031] To improve antenna gain, such as Figures 1-3As shown in Figure 4, a reflector 105 is fixedly installed on one side of the outer wall of the substrate 101. A reflective arc surface 106 is provided on one end of the outer wall of the reflector 105. The height of the reflective arc surface 106 is greater than the height of the radiator 102. The reflective arc surface 106 and the radiator 102 are concentric. Two first ground planes 107 are fixedly installed on the bottom side of one side of the substrate 101. The two first ground planes 107 are respectively located at both ends of the microstrip line 103. The electromagnetic waves of the radiator 102 can be reflected and concentrated through the reflective arc surface 106 at one end of the reflector 105, thereby concentrating the energy of the antenna and improving the antenna gain. The height of the reflective arc surface 106 is greater than the height of the radiator 102, which can more fully concentrate the electromagnetic waves of the radiator 102, enabling the antenna to transmit signals stably.

[0032] In order for the antenna to work stably, such as Figures 1-4 As shown, a second ground plate 108 is fixedly installed on the outer wall of the substrate 101 on the side away from the first ground plate 107. Multiple connecting terminals 204 are fixedly installed on the top of the connector 202, and these terminals are respectively connected to the first ground plate 107 and the second ground plate 108. Connecting bolts 109 are threaded into the top of each of the two first ground plates 107. The two connecting bolts 109 penetrate the substrate 101 on the side away from the first ground plate 107 and are threadedly connected to the second ground plate 108. The tops of the first ground plate 107 and the second ground plate 108 are at the same height. The second ground plate 108 is U-shaped. The connecting bolts 109 penetrate the first ground plate 107 and the substrate 101 and are threadedly connected to the second ground plate 108, allowing the first ground plate 107 and the second ground plate 108 to be stably installed on the substrate 101. The surface of the ground plane allows for easy installation and removal of the first ground plane 107 and the second ground plane 108 by the operator. Furthermore, if damaged, the first ground plane 107 and the second ground plane 108 can be easily replaced. The connection between the connecting terminal 204 and the first ground plane 107 and the second ground plane 108 ensures stable antenna operation. The first ground plane 107 and the second ground plane 108 can serve as reference planes for the antenna system, providing a current return path for the radiating elements, ensuring the stability and efficiency of signal transmission. They also optimize impedance matching in the low-frequency band, improving the overall performance of the antenna. Additionally, the first ground plane 107 and the second ground plane 108 reduce interference from other communication systems to the UWB signal, achieving clean signal transmission by isolating different frequency bands, and improving the mechanical strength of the antenna.

[0033] The specific implementation scenario is as follows: During the manufacturing and processing of the antenna body 1, a radiator 102 is disposed on the surface of the substrate 101, and a microstrip line 103 is welded to the bottom of the radiator 102. Then, a reflector 105 is welded to one end of the substrate 101, so that the reflective arc surface 106 at one end of the reflector 105 can be concentric with the radiator 102. Then, a first ground plane 107 and a second ground plane 108 are installed on the surface of the substrate 101, so that the two first ground planes 107 can be located at both ends of the microstrip line 103, and the second ground plane 108 can be located on the substrate 101 away from the first ground planes 107. The outer wall of one side of the 07 is then connected by connecting bolts 109 through the first ground plane 107 and the substrate 101 and threaded to the inner wall of the second ground plane 108, thereby fixing the first ground plane 107 and the second ground plane 108. Then the connecting mechanism 2 is fixed to the bottom of the substrate 101 so that the inner core 203 can be welded to the microstrip line 103. The two connecting terminals 204 on one side are welded to the first ground plane 107, and the two connecting terminals 204 on the other side are welded to the second ground plane 108. Then the antenna is connected to other devices or modules through the external threaded connector 201.

[0034] When the antenna body 1 is working, the U-shaped groove 104 opened inside the radiator 102 can filter out 5G signals that overlap with WiFi. At the same time, the reflective arc surface 106 at one end of the reflector 105 can concentrate the antenna energy, which can effectively improve the antenna gain, thereby significantly improving the signal transmission distance and quality. This embodiment specifically solves the problems of short signal transmission distance and poor signal in the prior art.

[0035] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
